Özet
Introduction: Glomus tumors are neoplastic tumors that originate from neural crest. They are the most common paragangliomas
of head and neck region. Early surgery should be applied to prevent invasion and metastasis. Surgical approach should be
planned according to Shamblin classification. Surgery aims to excise entire mass and maintain continuity of arterial structures.
Methods: Patients who underwent surgery in our clinic between 2008-2018 were evaluated. The standard protocol was not
applied for preoperative evaluation. Generally, diagnosis was made by USG, CTI, MRI. All tumors were categorized with
Shamblin classification. The follow-up of patients from internation to discharge was evaluated retrospectively.
Results: In our clinic, 31 female, 7 male, 38 patients with average age of 45 years were operated in 2008-2018. Most of the
patients applied for a mass in the neck. According to Shamblin, 36.5% of lesions were type I, 53.6% type II, and 0.9% type III.
The mass was completely removed in patients with type I lesions. In 27% of those with type II lesions, the mass was removed
by tying ECA branches. In two of patients with type III lesions, ICA was excised and the saphenous graft was interposed, the
other patient’s vagus was cut and mass was removed primarily. During follow-up, right hemiplegia developed in one patient,
vocal cord paralysis in two patients, dysphagia in two patients.
Conclusion: Glomus tumors are often noticed with a mass in neck. Biopsy is contraindicated due to dense vascularity and
proximity to vascular structures. Angiography is the gold standard in preoperative evaluation. Ultrasound is noninvasive and
provides good anatomical information. Color Doppler evaluates vascularity of tumor. Today, CTI and MRI have replaced
angiography.
